BFlower Four Layer Black Color Disposable Charcoal Activated Carbon Mask Filter - 50 Pieces (Each Piece is Individually Packed)

Comparable to the original Yamde. The corners are unfinished, it would be better if it were tucked under it can sometimes scrape the skin. The wire in the nose section is short, but my nose is small so it isn't a great problem. Not as thick as exoected, smells come through. But they are individually wrapped in a sturdy ziplock type bag. Smells slightly like glue, don't they all. Did not irritate skin. Will be restocking from this brand.
